A metaphor
A kind of computing – SaaS
The new version of the Web
My current version of Internet Explorer is
IE 7.0.5730.13
This is referring to significant changes in the way the
internet operates
Not just a pathway for communication and trading
information
A workspace
A data center
A desktop that is accessible from anywhere
Tagging is naming and describing
Tagging is related to meta data – behind the scenes
organization
Tagging is the “new” folder
Tagging let’s you put your document in the
equivalent of many folders at one time
Open=Free and Accessible
Source=Code Source
Who Cares? Microsoft, Google, and Me
Open Source is not just about showing code. It is a
philosophy that insists that this code must remain
open for others to see, build upon and distribute
without discrimination against persons, groups, or
fields of endeavor.
Let’s talk about Open Source and Open Content for a
few more minutes
Who is Microsoft’s biggest competitor?
The competition is the Cloud.
1. Operating systems - Ubuntu
2. Office packages – Open Office, Google Apps
3. Image manipulation – Gimp
We have been talking about Open Source
Software. Now let’s talk about Open Content or
Open Education.

reassessment of access to education and leading
to what has been termed Open Educational

Research-Quality Web Searching
Googling
Is this a verb?
• Search Google effectively and precisely

Before you search:
“Crawls” pages on the public web
Copies text & images, builds database
When you search:
Automatically ranks pages in your results
Word occurrence and location on page
Popularity - a link to a page is a vote for it
~ 200 factors in all!
Think “full text” = be specific

Use academic & professional terms
domestic architecture vs. houses
genome society

association, research center, institute,
directory, database

Anyone can put up a web page
Many pages not updated
No quality control
most sites not “peer-reviewed”
less trustworthy than scholarly
publications
Look at the URL - personal page or site ?
~ or % or users or members
Domain name appropriate for the content ?
Restricted: edu, gov, mil, a few country codes (ca)
Unrestricted: com, org, net, most country codes (us, uk)
Published by an entity that makes sense ?
News from its source?
www.nytimes.com
Advice from valid agency?
www.nih.gov/
www.nimh.nih.gov/
Can you tell who wrote it ?
name of page author
organization, institution, agency you recognize
Credentials for the subject matter ?
Look for links to:
“About us” “Philosophy” “Background” “Biography”
Is it recent or current enough ?
Look for “last updated” date
Text
possibly forged ?
why not a link to published version ?
Sources
documented with links, footnotes, etc.?
do the links work ?
Evidence of bias
in text or sources ?
Search the URL in alexa.com
Click on “Overview”
Who links to the site? Who owns the
domain?
What did the site look like in the past?
(Wayback Machine)
Which blogs link to it? What do they say?
Try the URL in Google Blog Search
See what links are in Google’s “Similar pages”
Look up the page author in Google
Was the page put on the web to
inform ?
persuade ?
sell ?
as a parody or satire ?
Is it appropriate for your purpose?
All that said, who do we trust?
The Encyclopedia Britannica is written by experts
Wikipedia is written by the crowd.
Which is
better?
BBC says Wiki
What Wiki says
What others say
Do one of the following:
Which one is the real website of the World Trade
Organization?
World Trade Organization http://www.gatt.org/
World Trade Organization http://www.wto.org/
Which one is the real website of the White House
http://www.whitehouse.gov/
http://www.whitehousehistory.org/
Do a search using Google, then Yahoo and compare
the difference.
We defined tagging earlier. Now let’s look at it a
little further.
Create a free account on delicious
This one is called TrendsandIssues
The Password is trends12
http://delicious.com/tag/poverty
http://delicious.com/tag/ + word you want
to search for
depression
http://delicious.com/tag/poverty/depression
The social aspect of this process is what
gives this the term folksonomy.
This is the symbol that
identifies a site that can
be tracked using an RSS
reader.
